HYDRAULIC DRILL.
SPECIFICATION forming part of Letters Patent N o. 735,769, dated August 11 1903.
Application filed December 17,1902. Serial No. 135,566. (No model.)
The present invention appertains to the class of drillsl designed for boring deep kwells and in operation having a vertical reciprocatory movement imparted thereto from the surface by Inechanical appliances such as generally employed in deep-well-drilling machinery, the drill being longitudinally bored to deliver the water to the bottom of the opening being formed.
This invention provides a longitudinallybored drill having an enlarged point andv lateral ducts leading from the lower end of the longitudinal opening of the drill through;A
the sides thereof in rear of the enlarged point, said ducts inclining either upwardly or downwardly, as desired.
The invention will be more particularly set forth hereinafter and claimed an d is shown in the drawings hereto attached, in which- Figure l is a side elevation of a drill embodying the invention, the same being shown attached to a tubular drill-rod. Fig. 2 is a vertical central section of the drill on a larger scale, showing the lateral ducts upwardly inclined. Fig. 3 is a view similar to Fig. 2, showing the lateral ducts downwardly inclined.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
The drill l has its point enlarged so as to provide a bore or opening of larger diameter than the body of the drill vor the drill-rod, so as to permit free operation of these parts in the formation ofthe well. The drill-point is round and its end at and operates by driving the strata or formation ahead of the drill as the latter descends. In the event of the formation being rock or like hard substance the same is pounded, the chips or particles being carried olf by water, conveyed to the bottom of the bore or opening through the tubular drill-rod and the longitudinal open.- ing and lateral ducts of the drill.
The drill-rod 2 is coupled to the drill in any way, and, as shown, the upper end of the drill is reduced to form a shank, which is externally threaded for reception of the coupling by means of which the union or joint is effected. Thelongitudinal opening 3, formed central of the drill, terminates a short distance from the end thereof, and lateral ducts 4 lead therefrom through the sides of the drill.
These ducts may incline upwardly, as shown in Fig. 2, or downwardly, as shown in Fig. 3, and may be provided in any number. In the form of drill havingthe ducts upwardly inclined the water has an initial upward circulation imparted thereto. In the form of drill shown in Fig. 3 the water is directed downward, thereby assisting in washing away the drillings or loose particles and keeping the opening clear, thereby facilitating the operation, particularly in drilling through stone and like hard formations.
